General Relativity models
a vast, blank, four-dimensional canvas,
devoid on sentience.

Classical Physics defines the minute spots on this canvas where
sentient man is active, and gives sentient man the tools he needs
to draw upon the vast blank canvas.

The bottom line is
use General Relativity
if you want to model a blank, 4D, canvas,

and use Classical Physics, and Quantum Mechanics
if you are interested in tiny spots on the
four-dimensional canvas where sentient beings are active,
or if you want to shape your own world.

I suggest that as the universe is almost entirely
a vast, blank, four-dimensional canvas,

and as the activities of sentient beings
are tiny spots on this canvas,

that it is most productive
to focus on the spots
rather than on the vast sameness.
